摘要
为了开展江西省干热岩资源选区评价,选取岩浆岩类型多且出露面积大的赣东南地区为研究区,通过野外地质调查采集地表及钻孔样品进行岩矿鉴定、地球化学分析,并计算岩体生热率。研究结果显示,赣东南地区岩体生热率随岩体时代从老到新,呈现升高的趋势;燕山期岩浆岩生热率在赣东南地区平面上呈现南高北低、西高东低的明显规律;龙南地区热参1井岩体垂向上表现为生热率随深度增加而增加;大余崇义上犹地区和龙南地区岩体生热率较高,可作为江西省干热岩勘查优选有利区。研究成果可为江西省进一步开展高放射性产热型干热岩评价工作提供依据。
In order to evaluate dry hot rock resources in the Jiangxi province,many types of magmatic rocks largely outcropped in the southeast of Jiangxi province are selected to be studied.Based on the field geological survey,surface and drill core samples are collected for rock-mineral identification,geochemical analysis.In addition,the heat generation rate of the rock mass is calculated.The results show that the heat generation rate of the granite in the southeastern Jiangxi is increasing with the age of the granite.At the same time,the Yanshanian magmatic rock heat generation rate in the plane of southeast Jiangxi shows the obvious rules of high in the South,low in the North,high in the West and low in the East.In the vertical direction,the heat generation rate of the granite of the No.1 well in Longnan area increases with the increase of the depth.The Dayu-Chongyi-Shangyou and Longnan area can be used as the favorable areas for dry hot rock exploration in Jiangxi Province because of their high heat generation rate.The results of this study will provide a guidence for the further evaluation of high radioactive heat producing dry hot rock in Jiangxi province.
